Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED displays, and in particular to an anti-glare protective cover for LED displays. Background Technology
[0002] LED displays are flat panel display devices that use light-emitting diodes (LEDs) as the core light-emitting units. By controlling the on / off state of semiconductor LEDs, red, green, and blue LED chips are arranged in a certain proportion to form pixels, and a large number of pixels form the display image. With its characteristics of high brightness, wide viewing angle, long lifespan, and low power consumption, LED displays are widely used in advertising screens, conference center displays, transportation hub information screens, and other scenarios.
[0003] However, most LED displays currently lack anti-glare design. In strong light environments, such as indoor strong light, the screen surface is prone to strong reflections, which will lead to blurred display content, reduced contrast, and consequently affect the viewer's visual experience and information acquisition efficiency. Direct light can also cause visual fatigue and even temporary blurred vision. To address these issues, we propose an anti-glare protective cover for LED displays. Utility Model Content
[0004] The purpose of this invention is to provide an anti-glare protective cover for LED displays to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: An anti-glare protective cover for an LED display screen includes a protective cover body. A silicone top sheet is fixedly connected to one side of the protective cover body. Two threaded holes are opened on the outer surface of the silicone top sheet of the LED display screen body on one side of the protective cover body. Locking screws are threadedly connected to the inner walls of the two threaded holes. Two threaded fixing seats are fixedly connected to one side of the LED display screen body, and the outer surface of the locking screw is adapted to the inner wall of the threaded fixing seat.
[0006] In a further embodiment, two flexible adhesive sheets are fixedly connected to the outer surface of the protective cover body, and two adhesive areas are provided on the outer surface of the LED display screen body.
[0007] In a further embodiment, a limiting seat is fixedly connected to the outer surface of the LED display body, and a limiting block is fixedly connected to the bottom surface of the silicone top sheet, with the bottom end of the limiting block extending into the interior of the limiting seat.
[0008] In a further embodiment, the inner walls of both threaded fixing seats are fixedly connected with elastic buffer sheets.
[0009] In a further embodiment, the protective cover body includes a high-transmittance acrylic sheet, one side of which is provided with an anti-glare layer, and one side of which is provided with a scratch-resistant and wear-resistant layer, wherein the anti-glare layer is a nano-level anti-glare coating.
[0010] In a further embodiment, the size of the protective cover body is adapted to the size of the display area of the LED display screen body.
[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model's protective cover, through the cooperation of limiting blocks and limiting seats, and the fixing method of using locking screws to screw into threaded fixing seats through threaded holes, as well as the enhanced adhesion of flexible adhesive sheets to the adhesive area, can form a multi-layered stable structure. This allows the protective cover body to be firmly installed and fixed in the display area of the LED display body, ensuring that the protective cover body is always facing the display area, thus guaranteeing the stability of the glare protection effect. Through the design of the protective cover body, incident light can be decomposed into multi-directional diffuse reflection light, solving the problems of screen reflection and blurred display content under strong light in the background technology, possessing anti-glare characteristics, and enhancing the applicability of the LED display body in various scenarios.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-4In this utility model, an anti-glare protective cover for an LED display screen includes a protective cover body 1. A silicone top sheet 2 is fixedly connected to one side of the protective cover body 1. An LED display screen body 3 is provided on one side of the protective cover body 1. Two threaded holes 4 are opened on the outer surface of the silicone top sheet 2. Locking screws 5 are threadedly connected to the inner walls of the two threaded holes 4. Two threaded fixing seats 6 are fixedly connected to one side of the LED display screen body 3. The outer surface of the locking screws 5 is adapted to the inner wall of the threaded fixing seats 6. Elastic buffer plates 7 are fixedly connected to the inner walls of the two threaded fixing seats 6. By screwing the locking screws 5 through the threaded holes 4 into the threaded fixing seats 6, a mechanical lock can be formed to prevent the protective cover body 1 from detaching from the LED display screen body 3 due to external forces such as vibration and collision. The elastic buffer plates 7 in the threaded fixing seats 6 can absorb the tightening force during installation and the impact force during use, avoiding component wear caused by hard contact and extending the service life of the overall structure.
[0018] In a further embodiment, two flexible adhesive sheets 10 are fixedly connected to the outer surface of the protective cover body 1, two adhesive areas 11 are provided on the outer surface of the LED display body 3, a limiting seat 8 is fixedly connected to the outer surface of the LED display body 3, a limiting block 9 is fixedly connected to the bottom surface of the silicone top sheet 2, and the bottom end of the limiting block 9 extends into the interior of the limiting seat 8. By embedding the limiting block 9 into the limiting seat 8, the installation position of the protective cover body 1 can be quickly determined, avoiding the display area being blocked or the protection being misaligned due to offset. The cooperation between the flexible adhesive sheets 10 and the adhesive areas 11 enhances the tightness of the fit between the two and prevents stray light interference from gaps.
[0019] In a further embodiment, the protective cover body 1 includes a high-transmittance acrylic sheet 101. An anti-glare layer 102 is provided on one side of the high-transmittance acrylic sheet 101, and a scratch-resistant and wear-resistant layer 103 is provided on the other side of the anti-glare layer 102. The anti-glare layer 102 is a nano-level anti-glare coating. The size of the protective cover body 1 is adapted to the size of the display area of the LED display body 3. The high-transmittance acrylic sheet 101 uses polymethyl methacrylate as its core material. Its principle is to reduce light scattering through the regular arrangement of polymer chains, while simultaneously using a precision molding process to reduce surface roughness, ensuring that the light from the LED display body 3 is virtually undamaged. The anti-glare layer 102, made of nano-sized silica and silicone resin composite coating, provides a foundation for image clarity. By constructing a micron-level uneven structure on the coating surface, the incident strong light is diffusely reflected on the surface, decomposing the concentrated reflected light into multi-directional weak light, thereby eliminating glare without affecting the penetration of normal display light. The scratch-resistant and wear-resistant layer 103 is mainly composed of silicon carbide nanoparticles and polyurethane resin, which are uniformly dispersed in the resin to form a hard surface layer that can resist daily friction and minor impacts, preventing the anti-glare layer 102 from being scratched. At the same time, the flexibility of polyurethane can alleviate impact stress and extend the overall service life.
[0020] The working principle of this utility model is as follows: First, the protective cover body 1 is connected to the LED display body 3 through the silicone top sheet 2. During the connection, the limiting block 9 is embedded in the limiting seat 8 to achieve positioning, so as to avoid the protective cover body 1 from shifting and affecting the display effect. Then, the locking screw 5 passes through the threaded hole 4 and is screwed into the inside of the threaded fixing seat 6 to prevent the structure from loosening due to long-term use. Then, the flexible adhesive sheet 10 and the adhesive area 11 are further bonded to enhance the fit and ensure that the anti-glare layer 102 is always facing the display area. Next, the main body 1 of the protective cover is composed of a high-transmittance acrylic panel 101, an anti-glare layer 102, and a scratch-resistant and wear-resistant layer 103. The anti-glare layer 102 adopts a nano-level anti-glare coating, which can scatter strong light through a micro-concave-convex structure and reduce the reflection on the screen surface. When strong light shines on it, the anti-glare layer 102 can decompose the incident light into multi-directional diffuse reflection light to avoid concentrated reflection and glare. At the same time, the high light transmittance of the high-transmittance acrylic panel 101 ensures that the displayed content is clearly visible.
[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
